Harmonious Colors

Choose flowers that are of the same color family. For instance, pink, red, and purple flowers can create a harmonious display.

Contrasting Colors

Choose flowers that are opposite on the color wheel, such as purple and yellow or blue and orange. These colors create a bold and striking display.

Choose flowers that are of the same color but different shades, such as light pink, medium pink, and dark pink. This creates a subtle and elegant display.

Tall flowers, such as snapdragons or salvia, add height to your window box display.

Medium Flowers

Mix Different Flower Types

Consider mixing different types of flowers in your window box display. Here are some options:

Combining Annuals and Perennials

Combining annuals and perennials in your window box display provides a variety of color and texture. Annuals bloom for one season, while perennials come back year after year.
